Compat 2021 yielded great results in improving cross-browser compatibility. Chrome 97 introduced the WebTransport API. Firefox 96 comes with improved performance and security. Safari 15.2 and Safari Technology Preview 137 rolled out to users. Ember 4.0 and Jasmine 4.0.0 lead the updates section and don't forget to apply the January Security Updates for your Node installation.

Compat 2021 Holiday Update

I was glad to see all major browser vendors come together to work on the Compat 2021 initiative. And the results are visible for us all. Where 2021 started with scores between 64 and 69 for the stable versions, now all browsers pass the 90 points threshold.

The end of the year announcement of the Chromium team gives us more details on each focus area. The initiative is planned to continue in 2022 as well, under the name Interop 2022. Discussions are underway to decide the focus points.
